c crains. (ci. zia-oi) This invention relates to a paper roll stand or reel for supporting heavy rolls, such as are used to supply paper to printing presses.

The principal objects of this invention are to provide means for moving the paper roll supports on the stand or reel sideways in a very simple manner, easily and quickly operated and to provide this device in such a form that it may be used either'for moving one end support toward and from the other to provide for supporting rolls of dierent lengths, or for adjusting the rolls for side register.

Other objects and advantages of the invention will appear hereinafter.

Reference is .to be had to the `accompanying drawing, in which Fig. 1 is an end view of a reel having means for supporting a plurality of web rolls showing a preferred embodiment of this invention .applied thereto;

Fig.'2 is a side view showing how the reel can carry full width or fractional width rolls;

"in the printing oflarge newspapers, paper is fed to presses from very heavy web rolls which, in most cases, are carried on a support comprising a reel which can be turned to bring a new roll into position for delivering its web to the press by the rotation of the reel. Full width paper rolls are usually four pages wide, the web being slit in the middle and one web superimposed on the a other to give a two-page wide newspaper. Often the proper number of pages cannot be obtained by using full width rolls and a fractional width roll has to be used. The adjustment of the reel for fractional width rolls necessitates the moving in of one or both of the spiders on the paper roll stand. Sometimes it happens also that the width of a paper roll in a particular stand must be changed between editions. The present method of moving these spiders on the paper roll stand is a crude one which requires-considerable time to operate and also a great deal of effort on the part of the operators.

This invention is designed to provide a shifting device for moving the support for the end of the rolls along the reel in a simple, quick and easily operated manner. Also the same mechanism may be used for adjusting the rolls for side register.

In the form shown, two pedestals are mounted on the base plate and these pedestals may both be stationary. it the top they carry a shaft 11 which has mounted upon it supports 12, shown in the form oi three-arm spiders, for supporting in this case three web rolls. This shaft is rotated by power through a worm wheel 13 or the like fixed to it. in the present case the shaft l1 is provided with two keyways 1li therein, one extending in from one end and the other from the other. The supports 12, whether in the form of spiders or arms, are

provided with projections 15, one extending radially into Aeach of these keyways. These projections constitute feathers or keys to hold the supports 12 in fixed angular relation to each other and to the shaft. In this case one of the projections 15 extends into the shaft from one side and the other from the opposite side. They are perforated and screw-threaded to cooperate with a pair of lead screws 16 located in the shaft.

One lead screw, the one on the left, carries a spacing collar 17 and also a gear 18. These two elements are located on opposite sides of a bracket 19'which is attached to the hub of the worm wheel 13 and prevents any end motion of this lead screw. A motor 20 is mounted on the hub oi the worm 8C, wheel 13 and on its vshaft is a pinion meshing with the gear 18 to drive the lead screw to which this gear is iixed. At the other end the same conditions exist, the second motor being used to drive the other lead screw.

The operation of either one of these motors will rotate its lead screw which will cause the spider i2 at that end to move forward or back along the shaft as desired in accordance with the direction of rotation of the motor. The motor may be opergo ated by push buttons first in one direction and then in another in any Well known way.

From inspection of Fig. 2 it will be seen that when it is desired to run a fractional ywidth roll the spider or support 12 on one end can be moved 95 along the shaft until the proper distance is secured between the two spiders and the reel can be run with the fractional width rolls.`

Another feature of this invention is to operate spiders in the same direction to adjust the position of the paper rolls for side register.

These two objects are accomplished therefore by comparatively simple mechanism which requires no effort on the part of the operator and operates expeditiously so that very little time is absorbed in its manipulation. The change can be made without materially delaying the operation of the press which is an important feature ih all newspaper plants.

the two motors simultaneously to feed the two 100 The invention has been described as being ernployed in connection with the web rolls of a newspapcr printing press but it can be used for supporting and adjusting heavy rolls for any purpose for which it may be desired.

Although I have illustrated and described one form of the invention I am aware of the fact that inodications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited in this respect but what I do claim is:-

1. In a web roll reel, the combination with a pair of supports, a shaft rotatably supported thereby, means for rotating said shaft, a pair of spiders carried by said shaft, said shaft having a pair of keyways extending -therealong, each spider having a projection extending into one of said keyways for insuring the proper relation of the spiders to each other and to the shaft, said projections being longitudinally threaded'a pair of screws, one extending into the shaft from one end and the other from the other endv and each in screw-threaded engagement with one of said projections, whereby the rotation of either screw will move its spider along the shaft, and a pair of motors carried by the shaft-operating device and each connected with one of said screws for turning it so that the two spiders can be shifted along the shaft simultaneously in the same direction.

2. In a web roll reel, the combination with a pair of supports, a shaft rotatably supported thereby, means for rotating said shaft, a pair of spiders carried by said shaft, said shaft having a pair of keyways extending therealong, each spider having a projection extending into one of said keyways for insuring the proper relation of the spiders to each other and to the shaft, said projections being longitudinally threaded, a pair of screws, one extending into the shaft from one end and the other from the other end and each in screw-threaded engagement with one of said projections, whereby the rotation of either screw will move its spider along the shaft, and means connected with each of said screws for turning it.

3. In a web roll reel, the combination with a pair of supports, a shaft rotatably supported thereby, a pair of spiders carried by said shaft, said shaft having a keyway extending therealong, one spider having a projection extending into said keyway, said projection being longitudinally threaded, a screw extending along the shaft from one end, and in screw-threaded engagement with said projection, whereby the rotation of the screw will move its spider along the shaft, and means connected with said screw for turning it.

, 4. In a web roll reel, the combination of a pair of supports, a shaft rotatably supported thereby, means for rotating said shaft, a pair of spiders carried by said shaft, each spider having a longitudinal thread, a pair of screws, one extending part way along the shaft from one end and the other part way along it from the other end and each in screw-threaded engagement with one of said threads, whereby the rotation of either screw will move its spideralong the shaft, and means carried by the shaft-operating device and connected with said screws for turning them, each independently of the other to shift one of the spiders.

5. In a web roll reel, adapted to carry a plurality of full diameter rolls, the combination of a pair of supports, a central shaft rotatably supported thereby, a pair of spiders carried by said shaft, with power operated means for moving either or both of the spiders longitudinally of the central shaft. v

6. In a supporting device for a plurality of rolls, the combination of a rotary shaft, means, rotatable withbut movable along the shaft, for supporting the rolls, and power operated means for moving either or both supporting means longitudinally of the shaft.
